See also [Vaultwarden](https://github.com/dani-garcia/vaultwarden), a self-hosted, Rust implementation of the Bitwarden server and compatible with [upstream Bitwarden clients](https://bitwarden.com/download/).

Hardened, secure and offline password manager. Does not have cloud-sync baked in, deemed to be [gold standard](https://keepass.info/ratings.html) for secure password managers. KeePass clients: [Strongbox](https://apps.apple.com/us/app/strongbox-keepass-pwsafe/id897283731) *(Mac & iOS)*, [KeePassDX](https://play.google.com/store/apps/details?id=com.kunzisoft.keepass.free) *(Android)*, [KeeWeb](https://keeweb.info) *(Web-based/ self-hosted)*, [KeePassXC](https://keepassxc.org) *(Windows, Mac & Linux)*, see more KeePass clients and extensions at [awesome-keepass](https://github.com/lgg/awesome-keepass) by @lgg.

LessPass is a little different, since it generates your passwords using a hash of the website name, your username and a single main-passphrase that you reuse. It omits the need for you to ever need to store or sync your passwords. They have apps for all the common platforms and a CLI, but you can also self-host it.

A modern, open source password manager for individuals and teams. Beautiful, intuitive and dead simple to use. Apps available for all platforms and you can self-host it as well.

LibreWolf is an independent fork of Firefox that aims to provide better default settings to improve on privacy, security and user freedom. Mozilla telemetry is disabled, ties with Google (Safe Browsing) are severed, the content blocker [uBlock Origin](https://github.com/gorhill/uBlock) is included and privacy defaults are guided by research like the [Arkenfox project](https://github.com/arkenfox/user.js/).

Brave Browser, currently one of the most popular private browsers - it provides speed, security, and privacy by blocking trackers with a clean, yet fully-featured UI. It also pays you in [BAT tokens](https://basicattentiontoken.org/) for using it. Brave also has Tor built-in, when you open up a private tab/ window.

Significantly more private, and offers some nifty privacy features than Chrome, Internet Explorer and Safari. After installing, there are a couple of small tweaks you will need to make, in order to secure Firefox. For a though config, see [@arkenfox's user.js](https://github.com/arkenfox/user.js/). You can also follow one of these guides by: [Restore Privacy](https://restoreprivacy.com/firefox-privacy/) or [12Bytes](https://codeberg.org/12bytes/firefox-config-guide)

Tor provides an extra layer of anonymity, by encrypting each of your requests, then routing it through several nodes, making it near-impossible for you to be tracked by your ISP/ provider. It does make every-day browsing a little slower, and some sites may not work correctly. As with everything there are [trade-offs](https://github.com/Lissy93/personal-security-checklist/issues/19)

Probably one of the most popular, secure private messaging apps that combines strong encryption (see [Signal Protocol](https://en.wikipedia.org/wiki/Signal_Protocol)) with a simple UI and plenty of features. It's widely used across the world, and easy-to-use, functioning similar to WhatsApp - with instant messaging, read-receipts, support for media attachments and allows for high-quality voice and video calls. It's cross-platform, open-source and totally free. Signal is [recommended](https://twitter.com/Snowden/status/661313394906161152) by Edward Snowden, and is a perfect solution for most users.

Session is a fork of Signal, however unlike Signal it does not require a mobile number (or any other personal data) to register, instead each user is identified by a public key. It is also decentralized, with servers being run by the community though [Loki Net](https://loki.network), messages are encrypted and routed through several of these nodes. All communications are E2E encrypted, and there is no meta data.

XMPP, also known as Jabber, is an open standard for decentralized messaging that has been widely used for decades. It has actually been the basis upon which WhatsApp, Facebook's Chat and Google's Talk were built, but these companies (eventually) chose to remove the interoperability with other servers. Prominent XMPP clients support [OMEMO end-to-end encryption](https://en.wikipedia.org/wiki/OMEMO), which is based on the [Double Ratchet Algorithm](https://en.wikipedia.org/wiki/Double_Ratchet_Algorithm) that is used in Signal. For more hands-on information and to register an account you can visit [JoinJabber](https://joinjabber.org).

Matrix is a decentralized open network for secure communications, with E2E encryption with Olm and Megolm. Along with the [Element](https://element.io/) client, it supports VOIP + video calling and IM + group chats.

An end-to-end encrypted anonymous email service. ProtonMail has a modern easy-to-use and customizable UI, as well as fast, secure native mobile apps.

It has a free plan or a premium option for using custom domains (starting at $5/month). ProtonMail requires no personally identifiable information for signup, they have a [.onion](https://protonirockerxow.onion) server, for access via Tor, and they accept anonymous payment: BTC and cash (as well as the normal credit card and PayPal).

Free and open source email service based in Germany. It has a basic intuitive UI, secure native mobile apps and desktop email clients, anonymous signup, and an encrypted calendar. Tuta has a full-featured free plan and premium subscription plans allowing for custom domains (starting at $3/month). Tuta [does not use OpenPGP](https://tuta.com/blog/posts/differences-email-encryption/) like other encrypted mail providers, instead they use a standardized, hybrid method consisting of symmetrical and asymmetrical algorithms (with AES256, and RSA 2048 or ECC (x25519) and Kyber-1024). This causes compatibility issues when communicating with contacts using PGP. But it does allow them to encrypt much more of the header data (body, attachments, subject lines, and sender names etc) which PGP mail providers cannot do. The recent upgrades to Tuta's encryption algorithm makes data stored and sent with their service safe against attacks posed by quantum computers.

An open source, privacy-focused, encrypted email service supporting SMTP, IMAP, and API access

Mailfence supports OpenPGP so that you can manually exchange encryption keys independently from the Mailfence servers, putting you in full control. Mailfence has a simple UI, similar to that of Outlook, and it comes with bundled with calendar, address book, and files. All mail settings are highly customizable, yet still clear and easy to use. Sign up is not anonymous, since your name, and prior email address is required. There is a fully-featured free plan, or you can pay for premium, and use a custom domain ($2.50/ month, or $7.50/ month for 5 domains), where Bitcoin, LiteCoin or credit card is accepted.

There's also currently no anonymous payment option.

Free and open source email application developed and backed by Mozilla -it's secure, private easy and customizable. As of V 78.2.1 encryption is built in, and the [TorBirdy](https://trac.torproject.org/projects/tor/wiki/torbirdy) extension routes all traffic through the Tor network. Forks, such as [Betterbird](https://github.com/Betterbird/thunderbird-patches) may add additional features.

Mail client add-on, enabling the use of OpenPGP to easily encrypt, decrypt, verify and sign emails. Free and open source, Enigmail is compatible with Interlink Mail & News and Postbox. Their website contains thorough documentation and quick-start guides, once set up it is extremely convenient to use.

Quick tool, that enables you to test whether your mail client "reads" your emails before you've opened them, and also checks what analytics, read-receipts or other tracking data your mail client allows to be sent back to the sender. The system is open source ([on GitLab](https://gitlab.com/mikecardwell/ept3)), developed by [Mike Cardwell](https://www.grepular.com/) and trusted, but if you do not want to use your real email, creating a second account with the same provider, should yield identical results.

Tor provides robust anonymity, allowing you to defend against surveillance, circumvent censorship and reduce tracking. It blocks trackers, resists fingerprinting and implements multi-layered encryption by default, meaning you can browse freely. Tor also allows access to OnionLand: hidden services.

I2P offers great generic transports, it is well geared towards accessing hidden services, and has a couple of technical benefits over Tor: P2P friendly with unidirectional short-lived tunnels, it is packet-switched (instead of circuit-switched) with TCP and UDP, and continuously profiles peers, in order to select the best performing ones. I2P is less mature, but fully-distributed and self-organising, its smaller size means that it hasn't yet been blocked or DOSed much.
